Intake manifold gaskets

Posted by ks114 On 2015/4/3 16:52:54

Hi, I suspect that the intake manifold gaskets on my 1955 Patrician need replaced, due to the fact that I can't get a good adjustment on the idle air.
I will spray carb cleaner around the gasket areas to confirm this.
My question is, which manifold gasket should I use? Steel or composite?
Thanks!
